Referring no `'more'.par'ticlilarly. to the Adraw ing, the, numeral Il generallydesignates. a seat y which vis conventionally illustrated andfwhich is of the general. construction commonly used in buses, train coaches and like public conveyances,

such seatshaving abottom frame, to whichthe suDDQIting legs are f attached and which is indifcated'by the numeral 2.

In v accordance with .the present invention, the frame 2. has secured to.v the transverse bars. 3` which fornfapart of its construction. the legs, which. are f indicated .generally by the numeral 4; and which are of hollow form soas to provides.

housing forvthe'hereinafter. described securing mechanism. These legs may be shaped' from sintable sheet metal and they have the upwardly converging sidewalls 5 whicheare 'joined-atftheir Aal The invention willbe bestundcrstoodffroma consideration of. the following. detailed description taken in connectionwith theaccomp'anyinzdrawing, it. being. understoodhwever, thatthe vn'wex'nzicm.1s neurone considered as lnmted'by snecicillustrationor. description but' that suchv illustration and description ccmstituttjas7 erpreierred.A ernbodimentotI theinvention.

-Int-hedrawinow Fissi is aview in frontselevation. of a seat constructed in. accordance with.. the present inveuizioxnq f A forwardedges byltherounded front Wall, while atl their-rear edges they are angled to extend downwardly. and rearwardly and. arejoined hy the integralv rounded. back wall 'i'which has a downwardly andv rearwardly extendingv slope. The'upper edges of thefour walls of.. the hollowv legsare lsuitably secured asr by welding or in ,any other suitablev manner to thev frame harl 3,'.wl1ile1 the bottomof the leg structure isclosed bythe Ybottom wall 8. Thus it Will be seen'thatthe. legs are of `strezalxnlined form and. because of.the.r ear wardly.` sloping back. walls which.r extend beyond thefpnintv ofconnection betweenfthe topeof the leg. attheY rear thereof and the. frame, wil1. function to holdthe seats firmly and prevent any tendency tovv rearward. tipping.

A- portion ofv theoor structure. is indicated by` the numeralv 9 andain. accordance with the present invention. there are secured tothe floor two holding unitseach ofi which is indicated generally by the numeral-10, each of.,these.units 1 being located 'sol that itv may` extend upwardly throughthe opening I .Lin the-bottom:wallsrof;v

a leg. 1 Each'of the units I0 comprises an eye-bolt having a portion I2-which extends throughthe iioor and receives upon the threaded lower end thereof the lock nut I3, While the upper end or eye of the bolt which is indicated by the numeral i4, lies above the plane of the top of the floor.

Overlying the upper end of the eye-bolt is a box or housing I5 which is secured to the floor 9 by screws I6 or in any other suitable manner. The box extends upwardly into the hollow leg through the opening II thereof and the top wall is provided with an opening II` as shown in Fig. 2.

The eye I4 of the eye-bolt has extended therethrough a pivot pin I8 which pivotally secures to the eye-bolt the two downwardly convergent legs I9 of a yoke which is indicated generally by the numeral 2i). rlhis yoke as shown in Figs.

2 and 3 is relatively long and two legs extend upwardly into the substantially semi-circular portions 2I which are joined together by the ransverse loop or bar 22 so that the yoke also forms a hook-like structure.

-less there is provided a looking or securing means in association with each bolt 21 which comprises'a resilient metallic strap 34 which is pivotally secured at one end to the adjacent wall 5 by a rivet 35 or any other suitable means As will be readily understood the securingyoke 26 swings on the pivot i8 lengthwise ofthe leg or transversely of the seat from the front'to the rea;` thereof. Within the box I5 there is located at ,the back of the yoke a rubber bumper 23 and on the opposite side of the yoke from this bumper is a similar body 24 having la top flange portion 25 which extends across the opening I1 and constantly urges the yoke to swingY rearwardly against the block 23.

The side walls 5 of each leg have secured therein directly opposite or transversely aligned positions, the pair of guide collars 26, shown particularly in Fig. 3 and extending through these collars is a bolt 21 which lies directly above and parallel with the pivot I3 c-: the underlying unit.

This bolt 21 at one end has the head 2B while' the opposite end has threaded thereon nut 29.

At substantially midway between its ends the bolt 2l carries a collar 30 which is formed integrally with a hook finger 3l, the point of which describes a circle around the bolt when the latter is turned or rotated. The height of the bolt 2l above the adjacent pivot I8 is such that,v when the hook 3i is turned down asin Fig. 4 the looped portion of the yoke can be swung in to receive the bolt 21 and the yoke will straddle the hook.3i. The location of the bar portion V22 of the yoke, when the latter is -in disconnected position is such that when thehook-nger 3I is turned upwardly its point will pass through the yoke and around and over the bar 22 so as toestablish a connection between the hook and the yoke and at the same time the `yoke will lbe swung forwardly so that the bolt 21 will enter the looped portion of the yoke as shown in Fig. 2. In this manner the yoke willAbe securely connected with the bolt 21 which lies adjacent thereto and also the resilient flange 25 will be under compression so that when the bolt 21 is reversely turned so as to release the hook-finger from the yoke bar, the yoke will be forcedto the rear, to the position in which it is shown in Fig. 4 thus completely disconnecting the leg fromy the iloor. As will be readily appreciated the leg may then be lifted directly oir the adjacent unit III.

In order to facilitate positioning the leg proporly on the floor so that the units Il! Ymay enter` the openings II, without difficulty, the bottom 8.

of each leg is provided adjacent toits forward and rear ends with a centering pin 32 which; is adapted to engage in an opening 33 formedin thefloor.

From the foregoing it will be readilygseen that'V and which at its other end is provided with a flanged opening of polygonal contour corresponding to the contour of the head 2B of the bolt; This apertured end of the strap 34is engaged overthe adjacent bolt-head 28 by spring-- ing the strap outwardly away-from'the supporting wall and then turning the strap until it is in the properfposition where thefopening will receive the bolt-head when the strap is released to move back against the wall. l

Whatis claimed is: Y l; In a'chair or seat structure, a seatfbody, supporting 1e`gs` for the body each comprising a hollow housing having'a-lower portionjadapted to rest upon a supporting structure jsuch as a fioor, a rotatably supported hook-shaped finger mounted within each housing, means accessible from outside the housing for rotating the finger,V
